It acts like its not going all the way in overdrive . I have checked the gov, soloids and they ck ok. what do I do now ????????????????/ thanks Dan

 

You have to be going in excess of 26 mph for it to upshift. Check the overdrive relay. Do a search here, or on the internet and get yourself a book or at least a wiring diagram.

 

The cable should not be used to go in/out of overdrive. The cable is used only to disable or enable overdrive for certain driving conditions (I always leave mine engaged). To go into overdrive (when above the governor threshold speed Mike stated above), simply let off the accellerator momentarily and then accellerate. The OD will engage if all is wired correctly. If not, check the relay and governor for proper operation, in addition to wiring to kickdown switch and dist.
